Trial Outcomes & Findings for Evaluation of a Powered Surgical Stapler in Video-Assisted Thoracoscopic Lung Resection Procedures in Korea (NCT NCT02196675)

NCT ID: NCT02196675

Last Updated: 2016-07-15

Results Overview

Prolonged air leaks defined as longer than 5 days in continuous duration. Air leak was to be quantitatively assessed starting on the evening after surgery and then twice daily (during morning and evening rounds). Patients were instructed to perform standardized repeated forced expiratory maneuvers (coughing and blowing).

Recruitment status

COMPLETED

Target enrollment

105 participants

Primary outcome timeframe

Post-operative period through hospital discharge and follow-up at Day 30

Participant Flow

Individuals undergoing VATS lobectomy for suspected or confirmed Non-small Cell Lung Cancer, or individuals undergoing VATS diagnostic wedge resection in accordance with their institution's Standard of Care, and who meet study entry criteria, were enrolled in this study.

There was no assignment to treatment group given that this is a single arm study wherein the same device was used on all subjects. Results are presented for the overall cohort as well as by the individual procedure performed - lobectomy, wedge resection, or wedge resection with lobectomy.

PRIMARY outcome

Timeframe: Post-operative period through hospital discharge and follow-up at Day 30

Population: All subjects who consented to the study, had surgery for wedge resection, lobectomy, or wedge resection with lobectomy and were not converted to an open procedure

Prolonged air leaks defined as longer than 5 days in continuous duration. Air leak was to be quantitatively assessed starting on the evening after surgery and then twice daily (during morning and evening rounds). Patients were instructed to perform standardized repeated forced expiratory maneuvers (coughing and blowing).

Timeframe: Post-operative period through hospital discharge and follow-up at Day 30

Population: All subjects who consented to the study, had surgery for wedge resection, lobectomy, or wedge resection with lobectomy and were not converted to an open procedure and had complete data. One subject was missing the hospital discharge date, thus length of stay could not be calculated.

Determined as the length of time in days from hospital admission to initial hospital discharge
